Can I use an enum as a struct name?

I think it may be called literal?

enum packet_structures{
   PacketOne,
   PacketTwo,
   PacketThree
};

struct PacketOne{
 unsigned int packet_id;
};
struct PacketTwo{
 unsigned int packet_id;
};

struct PacketThree{
 unsigned int packet_id;
};

And let's say I have a general packet.

struct PacketGeneral{
 packet_structures TypeOfPacket;
};

PacketGeneral newPacket;

newPacket.TypeOfPacket = PacketOne;

Can I literally use that enum's name to typecast a char* to a struct (i.e PacketOne)? Without having to typecast with (struct PacketOne), how can I just typecast that same struct but with just the enumeration newPacket.TypeOfPacket?

No you cannot. Enums are used for storing literals and not identifiers.

No, at least not in C.

enum declares/defines constant identifiers.

So, you cannot use those same identifier again as structure tag name.

You can check that by compiling a program containing these declarations/definitions.
